Warning:
To reduce the risk of personal injury from hot surfaces, allow the power supply
or power supply blank to cool before touching it.
Caution:
For DC power supply, use only the ring terminals provided with the power supply
for customer-built power connections. Be sure no wire protrudes from the bottom of the ring
terminal barrels.
Warning:
Make sure that you connect the DC power feed cable to the power source in
the correct polarity. The cable's two wires are color-coded and numbered to indicate
polarity:
•
Black Wire (1):
negative (-) polarity
•
Red Wire (2):
positive (+) polarity
Note:
When connecting both Power Supply modules, the two AC power sources must
have the same ground potential.
Warning:
The device must be connected (by service personnel) to a socket-outlet with a
protective earthing connection.
Warnings:
•
Before extracting the Power Supply module, disconnect the power cord from the
module.
•
Before extracting the Power Supply module (after you have disconnected the
power cord), wait at least three seconds for the capacitors to discharge.
Note:
For DC power supply, the minimum nominal thread diameter of a pillar or stud type
terminal must be 3.5 mm (0.138 in); the diameter of a screw type terminal must be 4.0 mm
(0.157 in).
Note:
The DC power supply uses two power ring tongues and one ground ring tongue.
They are not interchangeable.
